ICE CREEPER.

Application filed October 5, 1925.

This invention relates to new and useful improvements in ice creepers.

One object of the invention is to provide an ice creeper which is simplein construction, and which can be conveniently and comfortably worn.

Another object is to provide an ice creep er which includes novel icegripping means movably mounted, and adjustable into and out of iceengaging position.

Another object is to provide an improved I means for supporting the iceengaging members, whereby said members are adapted for easy movementinto and outof ice engaging position.

Another object is to provide amovel locking means which operates to holdthe ice engaging members in either lowered or elevated position.

Other objects and advantages will be apparent from the followingdescription when taken in connection 'with the accompanying drawing.

In the drawing:

Figure 1 is a side elevation of an ice creeper made in accordance withthe present in` volition, with the ice engaging members in loweredposition, broken away.

Figure 2 is a top plan view of the same partly broken away to show thecrank shafts.

Figure 3 is an enlarged vertical longitudinal central sectional view onthe line 3-3 of Figure 2.

Figure 4 is a vertical transverse sectional view on the line 4-4 ofFigure 2, but showing the ice engaging members in raised position.

Referring particularly to the accompany ing drawing 10 and 11 representthe upper and lower sole plates of the device, which are held in spacedrelation by t-he connecting posts 12. Apertured plates 18 are secured toand extend between the peripheral edges of the plates 10 and 11, andreceive therethrough the shafts 14s. which have the cranks 15 on theirends, said cranks being arranged outwardly of the said plates 13. Aswill be seen from the drawing, there are two of these shafts la acrossthe front portion of the device, and two across the rear or heelportion, and extending around the toe'portion of the device is avertical metal plate or strip 16, which Ahas openings in its sideportions' receiving the outer ends the cranks 15LK A similar, butshatter Serial No. 60,602.

strip 17 is disposed around the heel portion of the device and hasopenings in its sides to receive the cranks 5 of the rear shafts la. Itwill be noted that the cranks stand or extend upwardly, when the Creeperinembers 1G and 17 are in elevated position. and in depressed positionwhen the said Creeper members are in lowered position, and that movementof said members longitildinally of the device, and then upwardly or downwardly, will cause said members to change their positions from iceengaging to elevated or non-ice-engaging. lhen moving the members 16 and1T into ice engaging position they are manipulated a ay from eachotherthat is, the forward one toward the toe of the device, and the rearone toward the heel of the device, and thence down wardly. A reversal ofsaid movements brings the said members intoelevated position. Tomaintain these members 16 and 17 in either elevated or lowered position.a means is disposed between said members whereby to prevent theirmovement toward or away from each other, said means including link 16secured to the outer end of the foremost of the cranks of the rear pair,and shown at 18, the forward end of said link being threaded through asleeve 19 which is carried on a cam lever 20, mounted on the rearmost ofthe forward cranks. This sleeve 19 is provided with a head 21 whichprevents said sleeve from moving` rearwardly through the bracket 22, ofthe cam lever. By rotating said sleeve, in said bracket, the link may bedra-wn in or let out, as the conditions require. Then properly adjusted,and the cam lever is thrown forwardly into horizontal position, members16 and 17 may be manually moved either into or out of ice engagingposition, and after having moved the n'iembers into such position, theoperator throws the lever rearwardly and downwardly into horizontalposition, thus locking the members against movement. There are two ofthese cam levers 20. one on each side of the device, and a link 16connected thereto and with the other end of the foremost of the rearshafts 1st. A yoke 23 is connected to the outer ends of the cam leversto permit the operator to operate both of said levers at the same time.

The lower edges of theni'embers 1G and 17 are formed with the srrations211, to pres vent slipping en the the An upwardly extending plete 25 issecured to the renr or heel portion of the upper plat-e l0, forembrneing' the heel of the wearer, Asuitable straps '2G being,` Carriedby said plete to be seourefl about the weerer`s toot. Similar strapsAare etteehetl to the toe portion ot the rleviee for engagement orer thetoe of the ivearers shoe.

Secured to the 'forward enel reeiwvnrd portions of the loiver face otthe lower plete ll ere the leather or rubber sole enel heel plates 2.7,r-:hereby to render the use et' the eleviee easy ivhen the toothedelements are in Velevated position.

lVhet is claimed is:

l. -An iee Creeping shoe Comprising n toot plate having dependinghangers, trans ese vshafts supported in kthe hangers and having terminalcrank portions, Creeper members disposed Jfor vertical movement withrespectI to the foot plete and receiving the sei-il Crank portionstherethr ugh, und means operetively Connected with the snifl Crnnliportions tor rocking;l the shafts to reise and lowerthe Creeper members.

2. An iee Creepingshoe Comprising a Jfoot plete having depending hangersat the toe and heel portions, transverse shafts rotatably supported inthe hangers and having terminal crank portions, Creeper membersvertieally momble with respect to the toe end heel portions ot' seid'toot plete, and means associated with the crank portions forsimultaneously raising' intl lowering seid Creeper members.

3.
